Always good to get an update , even though this is from October last year....

From 100% Injury Rate blog...

ATHLETES WITH ILLEGITIMATE KIDS

THE HEAVYWEIGHTSCalvin Murphy- 14 illegitimate kids by 9 women. You sir are our current champion.Travis
Henry- 9 kids by 9 women. All
of this by 28. Impressive. He is on pace to catch Calvin. The fact that he's broke from paying child support may slow him down though.
Ex-San Antonio Spur Willie Anderson - 9 illegitimate kids. If only his field goal percentage
had been as high as his impregnation rate.
Evander Holyfield - 9 illegitimate kids. Has more kids than brain cells left.
Jason Caffey - 8 kids by 7 women.Shawn Kemp - 7 illegitimate kids by 6 women. Gives his nickname of the Reign Man new meaning.
Derrick Thomas - 7 illegitimate kids by 5 women. He died at 33. Let's just leave it at that.

THE LIGHTNING FAST GROUPWillis McGahee - 3 illegitimate kids in 2 years in Buffalo. Not a lot to do in Buffalo, except make babies. Lots and
lots of babies.

THE GETTING A HEAD START GROUPGary Sheffield - Had 2 illegitimate kids by age 17. Added a few more later on in life.

THE THAT'S JUST WRONG GROUPElijah Dukes - recently impregnated a 17-year-old foster child. Also has 4 more illegitimate kids - making him a
middleweight as well.

KEEP YOUR EYE ON THIS GUY GROUP
Noel Devine - He's not an official member yet because he's not a pro. He's an incoming freshman at WV. But he had 2 illegitimate kids in
high school, and possibly more. Keep it Noel, a good start, but you've got a long way to go.

Some of these may be a tad off, as for example Shawn Kemp's wiki page says this:

Kemp has been subjected to many paternity suits, having fathered thirteen out-of-wedlock children with nine different women. This number is alleged to be
even higher.

THE LIGHTNING FAST GROUP
Willis McGahee - 3 illegitimate kids in 2 years in Buffalo. Not a lot to do in Buffalo, except make babies. Lots and lots of babies.

add Darren McFadden to that... i remember reading that he has a kid from one woman, two more on the way from another, and is currently in a paternity lawsuit
for a fourth from another woman... all probably within the past 2-3 years
